What is Gemma 4 26B A4B good for?

Gemma 4 26B A4B comes from Google; in uttapen you reach it with the model id "google/gemma-4-26b-a4b-it". It accepts up to 262,144 tokens of input per call, so a long document or several source files fit in a single request. A single response can run to 16,384 tokens. On price it sits in the "very cheap" band — cheaper than 69 and dearer than 337 of the other paid models in the catalogue.

What you get on top of text in, text out: it reads images directly, which makes it a real option for invoices, forms and screenshots; it supports tool calling, so it can invoke your own functions with valid arguments; it returns schema-valid JSON through response_format, ready to hand to your code; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.

Input runs at 20,309 toman per 1M tokens and output at 98,643 — output costs 4.9× input, so trimming the answer saves more than trimming the prompt. You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.

The closest alternative with the same capabilities from a different provider is Seed 1.6 Flash: Gemma 4 26B A4B works out roughly 1.1× more expensive, and its context window is the same size. Both run on the same key and the same code, so trying the other one is a single string change.

To make the figure concrete: 100,000 toman of credit buys roughly 645 thousand-word requests on Gemma 4 26B A4B , and every 1,000 toman is about 6,452 words of round trip. A job with one million input tokens and one million output tokens comes to 118,951 toman in total. Filling this model's 262,144-token window costs 5,324 toman on the input side alone, which is the real reason to keep conversation history short.

This id gets confused with "google/gemma-4-26b-a4b-it:free", because the underlying model is the same. The difference is the suffix: no suffix (the standard variant) against "free". Maximum answer length differs as well: 16,384 against 32,768 tokens. On parameters, this one takes frequency_penalty, logit_bias, logprobs, min_p.

Google has 45 models in our catalogue; the cheapest is Gemma 3 4B at 57 toman per thousand words and the dearest Google Gemini Pro Latest at 5,280. Among the less common parameters it accepts logit_bias, logprobs, min_p, repetition_penalty, top_k, top_logprobs — all through the standard request body. By context size the nearest option from another provider is Trinity Large Thinking at 262,144 tokens.

Where it makes sense: high-volume work such as classification, tagging and bulk summarising, logic puzzles and code review, pulling text and fields out of images, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
